LOOlVI FOR WEAVING WARP-FILE FABRICS.

To all whom it may concern:

Be it known that I, CHARLES BERNARD VHITE, a subject of the King of Great Britain and Ireland, and a resident of Manchester, in the county of Lancaster, Eng land, have invented new and useful Improvements in and Relating to Looms for Weaving VVarp-Pile Fabrics, of which the following is a specification.

This invention relates to improvements in the method of and appliances for producing warp pile or loom patterns described in the specification of prior Letters Patent No. 871382 granted to the present applicant.

The object of these present improvements is to so form, dispose, and operate the appliances described in the said specification as to render them easily applicable for the production of repeat spot or like designs upon cloth being produced in broad looms.

The accompanying drawings illustrate appliances disposed and arranged according to my invention and having two loop forming wires on each side of each repeat.

Figure 1 shows a loom furnished with the improved appliances in front elevation. Fig. 2 illustrates a cross section of the bars carrying the loop forming wires, and an end elevation of the devices by which such bars are operated. Fig. 3 is a view in plan of the loop forming wires for one repeat and their carriages and supports. Fig. 4 is a sectional view along the line w-3 of Fig. 8. Figs. 5 and 6 are views of the devices employed for throwing the loop forming wires in or out of action.

Similar letters of reference are used to indicate similar parts where they occur in the different figures.

A indicates the breast beam of the loom. Above it and extending across the loom or to the desired extent across'the loom are four slidable bars B B C C which are movable in 'the direction of their length across the warp. These bars carry frames D D and E E the bars B B carrying respectively frames D D and the bars C G carrying respectively frames E E As shown in Fig. 3 the frames D D are to the left of the pattern F being produced in the fabric G and the frames E E on the right.

Specification of Letters Patent.

Application filed 'February 16, 1909.

Patented Apr. 16, 1912. Serial No. 478,303.

These frames carry slides (Z d and e e which slides are furnished with loop forming wires 03 d and e e in the manner described and illustrated in the prior specification referred to. The different slides are provided with laterally projecting pins 9, the two pins on a pair of right or left hand slides projecting to the same extent as shown in Fig. 4. A. similar arrangement of frames and slides is used for each repeat of the pattern across the cloth, the same two bars B B carrying all the left hand frames and slides and the same two bars C G carrying all the right hand frames and slides. Thus all the right hand frames which are attached to the same bar move simultaneously and all the left hand frames which are attached to the same bar move together.

Above the breast beam is mounted a rocking shaft H furnished at suitable points in its length with arms or fingers J, one for each pair of right or left hand slides. This rocking shaft is rocked as desired from the jacquard mechanism through straps or the like K attached to pulleys on an intermediate shaft.

The sliding bars B B and G C are operated through cams L and levers M and links N. These cams are driven from the loom shaft 0 through suitable worm or other gearing as shown in Figs. 2 and 5 and are thrown into or out of gear by means of a suitable clutch which is actuated from the jacquard. In the form illustrated the loom shaft carries a worm O loosely mounted thereon.

O is a disk fiXed to the loom shaft. 0 is a further disk slidable on the shaft but rotating therewith and capable of being moved longitudinally thereon by a crank lever P which is lifted by the cord P from the jacquard. P is a latch lever for supporting the crank lever P and is also operated from the jacquard through a cord P The disk 0 has pins 0 on its inner face which pass through holes in the disk O and can engage with corresponding recesses in the face of the worm 0 With the different parts in the positions shown in Fig. 5 the worm O is locked to the loom shaft and rotates therewith to drive the cams L and actuate the slide bars B B, C 0 when the disk 0 is moved sufliciently to the left the worm is free on the loom shaft and the cams L are not rotated.

In Fig. 3 the whole of the bars B B C C are shown in their extreme left hand positions, the wires 0 a being thus shown in position for engaging with and forming loops in the pile, and the wires d (Z being shown in a position in which they cannot engage with the design warps. It will be seen that the left hand slide pins 9 are in the path of their finger J while the right hand slide pins are out of the path of their finger J.

The operation is as follows :Assume the left hand wires to be bound into the design and are now required to form further loops. The two bars B B are simultaneously moved to the left and carry their frames and slides to the position shown in Fig. 3. In such position the slide pins 9 are in the path of the finger J and upon the motion of the rock shaft H the finger J moves both slides (Z (Z to the extreme outer positions on their frames as shown by the slide d in dotted lines. The wires (Z (Z are now in a position to be moved to the right to enter the shed. The bar B is now moved to the right by its cam and the wire (l enters the shed and forms a loop in the warps, and occupying a position corresponding to that shown for the wires 0 6 The pin 9 is now out of the path of the finger J which has now returned to its illustrated position, and bot-h wires (Z cl" are beaten up by the lay Q. As the lay returns the finger J again moves and again moves the slide (Z and the wire (1 to their extreme outward positions so that the wire (Z can in turn be inserted in the shed by the movement of the bar B to the right. The slides e e are similarly moved to enable their .wires 6 e to be put into or withdrawn from the shed, the only difference being that their bars C C are moved to the left to put their wires in the shed and to the right to withdraw them and put the slides e and 6 into the path of the finger J. All the corresponding wires on the left of each repeat of the design across the cloth are simultaneously operated, as are also the corresponding wires on the right of the repeats.

Figs. 5 and 6 show the cam driving clutch in action. Then the clutch is to be disengaged the crank latch lever P is moved by the pull of the cord P from the jacquard and its upper end moves away from underneath the lever P. This lever then falls by its weight and the clutch is disengaged. When the cams are to be again rotated the cord P is pulled from the jacquard, the lever P is lifted to its illustrated position and the end of the lever P is returned by the spring 79 to again latch the lever P in its raised clutch gearing position.

The cams L have the requisite shape to move the bars B B simultaneously to the left and independently to the right, and to move the bars C 0 simultaneously to the right and independently to the left.

Instead of having two wires on each side of a repeat any other suitable number borne by a corresponding number of bars may be similarly used and operated.

The operation of the jacquard mechanism to effect the different operations described will be understood by any one acquainted with the art of weaving. Conveniently the jacquard can be prevented from operating the wires when the product-ion of a pattern is to cease by presenting an unperforated part of a card to the needles controlling the rocking shaft and the clutch respectively. After a sufiicient number of picks and when the loops which were last formed are firmly bound into the cloth the wires or those wires which are engaged with the loops in the cloth are withdrawn laterally by presenting a perforated portion of acard to the needle controlling the clutch and cam. When the wires are thus withdrawn an unperforated part of a card is again presented to the latter needle and the cams are again rendered inoperative. The stroke of the sliding bars may be varied by altering the relative lengths of the arms of the levers M by pivoting them at any one of several holes formed in their lengths. Then the formation of pile loops is to be resumed perforated parts of the cards are again presented to the rocking bar and clutch or cam needles in the proper sequence.
